);
var body = new BroadcastRequest
(
    new List<Message>
    {
      new TextMessage(type: "text", text: "hello"),
      new TextMessage(type: "text", text: "world!")
    },
);
var resp = await client.BroadcastAsync(body);

            altText: "test",
            baseSize: new ImagemapBaseSize(1040, 1040),
            actions:
              new List<ImagemapAction>
              {

var resp2 = await client.PushMessageAsync(body2);

Webhook echo example

dotnet add package Linebotsdkx.Webhook
dotnet add package Linebotsdkx.MvcUtility

public class LineController : ControllerBase
{
    [HttpPost]
    public async Task<IActionResult> Post()
    {
        if (!(await Linebotsdkx.MvcUtility.SignatureValidationAsync(this, "<YOUR_CHANNEL_SECRET>")))
        {
            // invalid
            return BadRequest();
        }
        var body = await Linebotsdkx.MvcUtility.WebhookResultDeserializeAsync(this);
        Console.WriteLine(body.Events); // webhook event objects from LINE Platform
        Console.WriteLine(body.Destination); // user ID of the bot
        foreach (var x in body.Events)
        {
            if (x is MessageEvent && x.Source is UserSource)
            {
                var messageEvent = x as MessageEvent;
                if (messageEvent.Message is TextMessageContent)
                {
                  var userSource = x.Source as UserSource;
                  var textMessageContent = messageEvent.Message as TextMessageContent;
                  var echoBody = new PushMessageRequest(
                      to: userSource.UserId,
                      messages: new List<Message>
                      {
                          new TextMessage(type: "text", text: textMessageContent.Text ),
                      }
                  );
                  await client.PushMessageAsync(echoBody);
                }
            }
        }
    }
}

Development

exec run.sh that will use openapi-generator generate code.
